The esp driver provides support for the NCR 53C90, 53C94 and 53C96;
Emulex ESP100, ESP100A, ESP200 and ESP406; and Qlogic FAS216 and FAS408
SCSI controller chips found in a wide variety of systems and peripheral
boards. This includes the Qlogic ISA and VLB SCSI host adapters, and the
Sun Fast SCSI buffered Ethernet for Sbus (FSBE/S, X1053A, Sun part #
For Qlogic PCI SCSI host adapters, use the isp(4) device.
The esp driver supports the following flags for use in config(1) files:
bits 0-7: disable disconnect/reselect for the corresponding SCSI
bits 8-15: disable synchronous negotiation for the corresponding SCSI
bits 16-23: disable tagged queuing for the corresponding SCSI target
"Target" is synonymous with SCSI ID number.
Note that SCSI tape drives should be allowed to perform
disconnect/reselect or performance will suffer.
